Abstract: This invention relates to solvents for extracting C1 to C4 carboxylic acids from aqueous streams. More specifically, the extraction solvents include one or more salts composed of a phosphonium cation and an arylcarboxylate anion. The extraction solvents may further include one or more non-ionic liquid organic solvents as an enhancer. The extraction solvents are useful for extracting aqueous mixtures containing one or more lower carboxylic acids, such as monocarboxylic acids, alkoxycarboxylic acids, and halogen-containing carboxylic acids.

Abstract: Iron-based homogeneous catalysts, supported by pincer ligands, are employed in the transfer hydrogenation of esters using C2-C12 alcohols as sacrificial hydrogen donors to produce corresponding alcohols from the esters. No external H2 pressure is required. The reaction can be carried out under ambient pressure.

Abstract: A transfer hydrogenation process for forming vicinal diols by hydrogenating 1,2-dioxygenated organic compounds using alcohols as the reducing agent instead of the traditional H2 gas. The transfer hydrogenation is carried out under milder conditions of temperature and pressure than is typical for ester hydrogenation with H2. The milder conditions of operation provide benefits, such as lower operating and capital costs for industrial scale production as well as savings in product purification due to the avoidance of by-products from exposure of reaction mixtures and products to high temperatures.

Abstract: Provided is a process for the preparation of certain 1,4-bicyclo[2.2.2]octane derivatives. The new synthetic procedure involves treating 1,4-dimethylene cyclohexane with an oxidizing agent in the presence of a transition metal catalyst to afford an oxo-substituted bicyclo[2.2.2]octane species. This intermediate structure can then be further derivatized. The processes of this disclosure thus affords a novel and simplified means for the commercial production of a wide variety of bicyclo[2.2.2]octane derivatives.
